Thomas,

Do you think it is worth explicitly stating the fact that time is a monotonically increasing function ?

I.e. TSA, when synchronizing to an external reference clock (e.g. GPS, ACTS, trusted/secure NTP server) MUST always skew and _never_ step back its internal clock ?

No. If there is a drift, then the TSU can stop for a while to generate time-stamp tokens until synchronisation with UTC is reached again and then go on.
